This rumored relationship could cause some drama among the Kardashian-Jenner clan as Kylie Jenner has been in an on and off-again relationship with Tyga. Rob and Blac Chyna have known each other for years, but stopped being friends once things started to get serious between Kylie and the 26-year-old rapper.

After the tweet sparked speculation that she was referring to Rob, Khloe clarified, writing: ""You guys do know I have about 100 family members correct? I was referring to a family member who just bailed out of doing my talk show today."

While Rob has been quite reclusive over the past few years, he does appear to be coming out of his shell a bit. Last week he shared a rare selfie, and according to his mom, Kris Jenner, he hopes to return to the family's hit reality show, Keeping Up With the Kardashians.

"He's still part of the show, he's had a year where he kinda wanted to chill," Kris said earlier this month. "He hasn't been feeling well -- we didn't really know why -- he was just diagnosed with diabetes. So, we're taking care of that."
